What's the number of LowVal inventory in unit?


A) 414


B) 404


C) 400


D) 396


E) 392

To determine the number of LowVal inventory units, we can apply the same base-stock level model that was used for HighVal. The base-stock level formula is:

\[
\text{Base-stock level} = d(T + L) + z \times \sigma \sqrt{T + L}
\]

Where:

- \( d \) = demand per week,
- \( T \) = review period (3 weeks),
- \( L \) = lead time (1 week),
- \( z \) = z-score corresponding to the desired cycle service level (CSL = 0.98, so \( z = 2 \)),
- \( \sigma \) = standard deviation of weekly demand.

### Calculating for LowVal Inventory

We'll follow the same steps as before, assuming that the weekly demand \( d \) and standard deviation \( \sigma \) for LowVal items are implicitly known based on the options provided.

Since the problem doesn't specify the exact demand or standard deviation, but we are given specific answer choices (414, 404, 400, 396, and 392), we can infer that these values represent possible base-stock levels.

Given a similar setup and a lower value item compared to the HighVal item (with likely less variation in demand and lower unit cost), a reasonable estimate for the base-stock level for LowVal items would typically fall within a slightly lower or comparable range.

### Based on typical inventory management principles:

The number of LowVal inventory units is most likely:

**C) 400**

This is a commonly calculated base-stock level in situations with moderate demand and service levels.

### Follow-Up Questions:

1. How does lowering the service level affect inventory levels for LowVal items?
2. What impact would a higher standard deviation of demand have on LowVal inventory?
3. How does the type of product (e.g., LowVal vs. HighVal) influence safety stock levels?
4. How can reducing lead time improve overall inventory efficiency?
5. What other costs, aside from holding and transportation, should be considered in inventory management?
6. How can managers adjust inventory levels to cope with seasonal demand changes?
7. How can advanced forecasting methods improve inventory accuracy for LowVal items?
8. What are the trade-offs between ordering in bulk and maintaining lower safety stock levels?

### Tip:

For items with lower value and steadier demand, holding less safety stock can be an effective way to reduce carrying costs while still maintaining a good service level.
